It's about time - a DEET-free insect repellent that really works! Natrapel® provides 12 hours of protection from mosquitos, ticks and other biting insects, thanks to it's CDC-recommended 20% Picaridin formula. Unlike ineffective DEET alternatives, Picaridin is the only formula that consistently shows equal or better performance than DEET in independent, clinical tests. Even better, Natrapel® 12-hour is completely safe on gear and will not melt clothing, jackets, fishing line, and other synthetic materials. 1oz. size is great for packs, purses, or pockets.
